## Aminopropyl silica gel was prepared from porous silica gel by reaction with yaminopropyltrimethoxysilane in toluene and was used for immobilizing chymotrypsin (EC 3.4.4.5) and human serum albumin. Immobilized chymotrypsin was used for the resolution of N-acetyl-Dt--phenylalanine and immobilized
It is shown that alkylchlorostannanes can be successfully used for synthesis of chemically modified silica. The hydrolytic stability of the materials obtained is studied. It is revealed that grafted layers of Et 3 SnCl and Et 2 SnCl 2 can be removed at pH values lower than 4, whereas silica modifica
